How to write and save html file in python? – Stack Overflow
This is what I know about writing to an HTML file and saving it:
html_file = open(“filename”, “w”)
()
But how do I save to the file if I want to write a really long codes like this:
1
Number | Square |
---|---|
<%= i%> | <%= i**2%> |

You can create multi-line strings by enclosing them in triple quotes. So you can store your HTML in a string and pass that string to write():
html_str = “””
Number | Square | <%= i%> | <%= i**2%> |
---|
“””
Html_file= open(“filename”, “w”)
(html_str)

As others have mentioned, use triple quotes ”””abc””” for multiline strings. Also, you can do this without having to call close() using the with keyword. This is, to my knowledge, best practice (see comment below). For example:
# HTML String
html = “””
# Write HTML String to
with open(“”, “w”) as file:
(html)
See for more details on the with keyword in Python.

You can try:
colour = [“red”, “red”, “green”, “yellow”]
with open(”, ‘w’) as myFile:
(‘‘)
(‘
(‘
%04d | %s |
‘)
(‘‘)

You can do it using write():
#open file with ** extension to write html
file= open(“”, “w”)
#write then close file

This lesson uses Python to create and view an HTML file. If you write
programs that output HTML, you can use any browser to look at your
results. This is especially convenient if your program is automatically
creating hyperlinks or graphic entities like charts and diagrams.
Here you will learn how to create HTML files with Python scripts, and
how to use Python to automatically open an HTML file in Firefox.
If you do not have these files from the previous lesson, you can
download programming-historian-5, a zip file from the previous lesson.
At this point, we’ve started to learn how to use Python to download
online sources and extract information from them automatically. Remember
that our ultimate goal is to incorporate programming seamlessly into our
research practice. In keeping with this goal, in this lesson and the
next, we will learn how to output data back as HTML. This has a few
advantages. First, by storing the information on our hard drive as an
HTML file we can open it with Firefox and use Zotero to index and
annotate it later. Second, there are a wide range of visualization
options for HTML which we can draw on later.
If you have not done the W3 Schools HTML tutorial yet, take a few
minutes to do it before continuing. We’re going to be creating an HTML
document using Python, so you will have to know what an HTML document
is!
One of the more powerful ideas in computer science is that a file that
seems to contain code from one perspective can be seen as data from
another. It is possible, in other words, to write programs that
manipulate other programs. What we’re going to do next is create an HTML
file that says “Hello World! ” using Python. We will do this by storing
HTML tags in a multiline Python string and saving the contents to a new
file. This file will be saved with an extension rather than a
extension.
Typically an HTML file begins with a doctype declaration. You saw
this when you wrote an HTML “Hello World” program in an earlier lesson.
To make reading our code easier, we will omit the doctype in this
example. Recall a multi-line string is created by enclosing the text in
three quotation marks (see below).
#
f = open(”, ‘w’)
message = “””
Hello World!
“””
(message)
()
Save the above program as and execute it. Use File ->
Open in your chosen text editor to open to verify that
your program actually created the file. The content should look like
this:
HTML Source Generated by Python Program
Now go to your Firefox browser and choose File -> New Tab, go to the
tab, and choose File -> Open File. Select You
should now be able to see your message in the browser. Take a moment to
think about this: you now have the ability to write a program which can
automatically create a webpage. There is no reason why you could not
write a program to automatically create a whole website if you wanted
to.
We automatically created an HTML file, but then we had to leave our
editor and go to Firefox to open the file in a new tab. Wouldn’t it be
cool to have our Python program include that final step? Type or copy
the code below and save it as When you execute it, it
should create your HTML file and then automatically open it in a new tab
in Firefox. Sweet!
Mac users will have to specify to the precise location of the
file on their computer. To do this, locate the programming-historian
folder you created to do these tutorials, right-click it and select “Get
Info”.
You can then cut and paste the file location listed after “Where:” and
make sure you include a trailing slash (/) to let the computer know you
want something inside the directory (rather than the directory itself).
import webbrowser
#Change path to reflect file location
filename = ‘file/Users/username/Desktop/programming-historian/’ + ”
_new_tab(filename)
If you’re getting a “File not found” error you haven’t changed the
filename path correctly.
_new_tab(”)
***
Not only have you written a Python program that can write simple HTML,
but you’ve now controlled your Firefox browser using Python. In the next
lesson, we turn to outputting the data that we have collected as an HTML
file.

Re-read and review Chs. 1-17
To follow along with future lessons it is important that you have the
right files and programs in your “programming-historian” directory. At
the end of each lesson in the series you can download the “programming-historian” zip
file to make sure you have the correct code. If you are following along
with the Mac / Linux version you may have to open the file and
change “file/Users/username/Desktop/programming-historian/” to the
path to the directory on your own computer.

How to write to an HTML file in Python ? – GeeksforGeeks
Python language has great uses today in almost every field, it can be used along with other technologies to make our lives easier. One such use of python is getting the data output in an HTML can save any amount of our input data into an HTML file in python using the following examples in two ways. Example 1: Creating an HTML file and saving the input data into roach:Creating an HTML ction_Name = open(“Complete_File_Name”, “File_operation”)Adding input data in HTML format into the (“Adding_Input_data_using_HTML_Synatx_separted_by_/n”)Saving the HTML ()Opening the HTML file from the saved is the implementation:Python3Func = open(“”, “w”)(“\n
